Description
Technical field
The utility model is particularly related to a kind of many typhoons power generator energy synthesis device.
Background technology
General wind power generation can divide two kinds of independent operating and electricity generation grid-connectings.
Independent operating is exactly not link to each other with electrical network, to small-sized plant, processing factory and family or village power supply, utilizes wind power generation as the main energy sources or the additional energy separately, reaches the purpose of energy-conserving and environment-protective.For the continuity that guarantees to power, available batteries to store energy or with the diesel engine parallel running.The single-machine capacity of this wind generator system is generally less than 100 kilowatts.Independent operating is 3-20 kilowatt to the single-machine capacity of family or village power supply separately.The more little installation of capacity safeguards that Vietnamese side just.
Electricity generation grid-connecting is to incorporate wind generator system into big electrical network, makes that the user on the electrical network can both enjoy green energy resource.The development wind power generation is the energy as an alternative, is the developing direction of new forms of energy.
The voltage-phase that alternating current generator sends, amplitude, frequency are all different, and simply paired running is difficult to realize; The voltage magnitude difference that DC generator is sent, simply paired running; The wind-driven generator paired running needs through numerous and diverse inversion transformation technique.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, and cost is low, and transportation, installation, maintenance are convenient, and capacity is big, system reliability is high, be easy to realize, but many typhoons of isolated operation power generator energy synthesis device.
Technical solution of the present utility model is:
A kind of many typhoons power generator energy synthesis device, comprise at least three small-sized wind power generators, its special character is: every small-sized wind power generator is through cable, system controller and corresponding dc separately excited motor connection, the corresponding dc separately excited motor of small-sized wind power generator, every dc separately excited motor output shaft connects with corresponding freewheel clutch respectively, the freewheel clutch output shaft is connected with mechanical transmission mechanism realizes the torque stack, the output shaft of mechanical transmission mechanism is connected with the power shaft of a synchronous alternating-current generator, also be coaxially connected with an autosynchronous motor on the power shaft of described synchronous alternating-current generator, the output of synchronous alternating-current generator is drawn the feeder ear of this many typhoons power generator energy synthesis device by system controller.

Above-mentioned many typhoons power generator energy synthesis device, described mechanical transmission mechanism is a gear drive.
The beneficial effects of the utility model are:
One, torque stack realizes many typhoons power generator energy synthesis
According to the mechanical property theory of dc separately excited motor torque and rotating speed, in permanent torque, permanent power, ventilation blower even load one regularly, make and rotation speed change can realize speed governing by changing armature voltage, exciting current or armature crosstalk resistance; Under the substantially invariable prerequisite of motor speed, voltage determines the output torque of motor conversely, and this voltage comes from small-sized wind power generator output.The utility model adopts dc separately excited motor process freewheel clutch and autosynchronous motor to drag synchronous alternating-current generator through mechanical transmission mechanism and realizes permanent rotating speed, by freewheel clutch each motor can both be done work, make the torque stack of multiple motors operation back by mechanical transmission mechanism, thereby energy synthesis and the capacity of realizing small-sized wind power generator are big.

Three, autosynchronous motor (feedback generating) accumulation of energy of being incorporated into the power networks indirectly
Light or wind-force is big when load, when the small-sized wind power generator generated output is big, the rotating speed that many dc separately excited motors compile is higher than the synchronous speed (trend) of autosynchronous motor, autosynchronous motor is operated in the regenerative braking of mechanical property second quadrant, be the generator operation state, to the electrical network feedback electric energy, active electric energy meter reverse rotation this moment, electrical network quite is a big accumulator, save and cost an arm and a leg, keep in repair frequent storage battery, can absorb on-the-spot have more than is needed electric energy endlessly, realize the maximization of Wind Power Utilization; Heavy or wind-force is little when load, small-sized wind power generator generated output hour, the rotating speed that dc separately excited motor compiles is equal to or less than the synchronous speed (trend) of autosynchronous motor, and autosynchronous motor absorbs electric energy from electrical network, drags synchronous alternating-current generator jointly.
Autosynchronous motor is received network operation, is the load of electrical network, does like this and does not violate national power supplies regulation, because they are not electric power systems.
Four, synchronous alternating-current generator gives load stable power supply that is equal to city's electricity quality and application place
Block supply below 100 kilowatts is power autonomous in the actual motion, when power quality is less demanding, can generate power for their own use, and need not use control appliances such as the complicated same period, phase place to be incorporated into the power networks.
When not having the condition of civil power, utilize the storage battery accumulation of energy, power to autosynchronous motor through inverter; Synchronous alternating-current generator is to charge in batteries in the work, is small-sized wind power generator to autosynchronous motor its energy source of powering.When not having wind, utilize the storage battery accumulation of energy to keep power supply.
The utility model utilizes the mechanical property of direct current machine directly to carry out energy synthesis, but simplified system, reduces cost, and transportation, installation, maintenance are convenient, is easy to realize; When a small-sized wind power generator fault, other small-sized wind power generators also can be worked, and this just improves the reliability of system.Native system has been useful in electric network source, no electric network source, but is fit to the actual application environment and the isolated operation of production, family and the village household electricity etc. of the large-scale plant of small-sized wind power generator work, middle-size and small-size machining factory, energy saving building.
